Need some Shader Analyzer of sort

Hello Everyone,

I have a bit of a problem. I am trying to get infos on compiled shaders in GLSL and by that I mean register quantity for parallelism. I can’t find any software , sdk etc … which is able to do that on a PC on a NVidia card. ShaderPerf seems to be what I need , but it is too old.
So if anyone knows how to get these informations , I would be extatic !
